With the Lexmark printers communication subsystem you MUST let the driver ask for you to plug in the printer. DO NOT plug the printer into the USB port until told to do so.

To fix a fouled install:(1) Uninstall the Lexmark drivers in Add Remove Programs(2) Shutdown the computer(3) Disconnect the printer from the USB port(4) Restart the computer(5) Run the Driver Installation software(6) Cancel ALL attempts by windows to auto install the printer(7) When the software asks for the printer connect it and continue

Hi,if you have the users manual (given that it has worked properly in the past) my suggestion would be to disconnect the printer from the computer/uninstall the current software/then with your manual in hand follow the guidance PRECISELY to reinstall the printer. If you do not have the manual it can be obtained (free) from the Dell site. Just before doing the uninstall/reinstall if you haven't already done so you might go to the Dell download site and install the latest drivers for the printer from there.Hope this helpsThanksDennis

try uninstalling all the usb hubs from the device manager and restart the computer but note that before you do that all the external devices should be unplugged. like printer , modem and anyother if there is any.
once you restart the computer automatically the hubs will get installed. also check with other usb ports.
if all this will not work then uninstall the printer driver compleately and after restarting the computer reinstall the printer driver .

Did you try reinstalling the software -- going to the manufacturer's website and get uptodate drivers? Uplug from the PC and eplug while both are turned off? Go to Device Manager update or rollback drivers, or uninstall and reboot to see if your PC will find it? You don't list what you have tried so it is hard to help you.

Mine seems to regularly to this. Bit of a pain, but everytime I uninstall it, then reinstall it, it works again for a while. Don't know if it's because I don't keep the printer plugged into my laptop all the time?? Try this anyway if you haven't already. Jen

From the very limited problem description, I 'll take a SWAG at the problem. It seems to me that the Lexmark provide software is communicating through the printer that you either have a solid failure on an existing Template or a Template was not closed properly.

If you haven't done any work on a Template, then I suggest that you uninstall the printer's software and reinstall it.
